4 Claims..

This invention relates to a closure for ashpitsangled cross sectidn.v The" frame thus Vformed and more particularly pertains to aframe for ashpit doors of the character designed to be set in the brick work of replace chimneys.

An object of the invention is to provide a construction in thedoorframe whereby the setting of the frame in brick work during the erection of a chimney will be greatly facilitated; such frames as now generally constructed being difcult to set inplace by reasonof lack of adequate means for eiecting anchorage of the framein the mortar employed in laying the bricks.

Another object is to provide a construction in an ashpit doorirame for eiecting anchorage of the frame in the mortar joint between adjacent layers of brick and whereby the frame may-'- be readily disposed in a properly aligned position.

Another' object is to provide an arrangement for the reception of headed pins for the purpose ofpositioning the Shanks of said pins in the mortar joint between one or more courses of brick and in which' the pin receiving slots are 215` so formed and arranged as to facilitate posi-k tioning of the pins in alignment with such mortarV joints.

A further object is to provide the side members of the frame with protruding anchoring pins -mounted for adjustment longitudinally of the frame side members. Withthe foregoing, objects in View, together with such other objects and advantages as may subsequently appear, the invention is carried`in.

3i to effect as illustrated'by way of example in the accompanying drawing in which:

^ Fig. l is a. perspective view of the ashpit closure as seen from the rear or inner side thereof depicting the manner of forming the doorframe in accordance with the invention;

Fig. 2 is a view in horizontal section taken on the line 2-2 of Fig. l showing the closure as set in brick-work;

Fig. 3 is a View in vertical section as seen .on the line 3--3 of Fig. 2;

Fig. 4 is a View in end elevation of a modified form of the doorframe.

Referring to the drawing more specifically A indicates generally the frame of a fireplace ashpit closure, which frame is rectangular in form and embodies a frontwall 5 formed with rearwardly extending upper and lower flanges 6 and l and end flanges 8 and 9, which flanges protrude from the inner margin of the frame thus forming the latter with an outwardly opening right of slots inv the sidemembers of the door frame- Los Angeles, calif v is fitted with a door B 'inclosed' thereby which isf mounted to swing horizontally relative tdthe frame on hinges vIll "and, II. `'lh'ei trarne and door construction above 'described is that cmmonly employed in ashpitvA closures 'nowg'c'en'erallyl in use; the parts being' ordinarily formedof cast metal and dimen'sioned 'relative to standard sizes"y of bricks employed in the erection of fireplace chimneys-so as to vfacilitate'building of fthe frame into the chimney'brickwork'informing-an ash# pit outlet. 'f v a brick wall in such fashion as.to\.form:'an arrchorage which will serve to securely;hold;the frame inj place ingproperfialignment withy lthe courses and `cuter Ifaces, ovf'rthebrick wall both during and after erection-thereof .fg g v when .the lower-flange .l of th'ejframe is-seated The ye1ongatedslots j C aref so arranged that;v

on a course Yof brickgandbricks ofa succeeding course are abuttedfagainst fthegend flanges-of the frame, pins jD` inserted through-theslots-Cl may be readilypositioned to. overlie the abutting bricks and mayl befseatedythereon. This. is ac-i complished; by. disposing .fthe lowerends 1 of the' slots less than the tlriickness of. a -brick fromf. theflangefl. v Likewise the slots'C, areA of such length as to extend across one ormore jointslbetweenadjacent courses. of bricksol as' -tofenable posi+a tioning of pins D to project into such joints. The slots C may be formedvin the flanges 8 and 9 as by molding or cutting them therein, l or may be formed as shown in Fig. 4 by a length of wire I 'I' arranged in spaced parallel relation to the end flange and having inturned end members I8 engaged in the'end flange as by casting the latter around the end members I8 or by inserting the end members in holes drilled in the edge of the ange.

In the application and operation of the invention the frame A is initially positioned with the lower iiange 1 thereof seated on a layer of mortar I2 spreadon top of a course of brick I3, as particularly shown in Fig. 3, and with the outer wall 5 of the frame overlying and abuttingthe 21"?, "ff I A and are positioned to abut against the end anges 8 and 9 of the latter; the bricks I4 beingl properly aligned for permanent setting in the wall. Pins D are then passed through the slots C from the inner sides of the end flanges 8 andA 9 with their heads abutting the inner faces of the :lianges and with their stems lying on the bricks `are imbedded.

A succeeding layer of brick I6 is then laid on the mortar on the bricks I5 and pins D are passed through the slots C and imbedded in the mortar joint between the bricks I5 and I6. The follow ing courses of brick are set in place in the usual manner to s urround the frame A in the chimney brick-work.

An important feature ofthe invention resides in the fact that on initially setting the frame A in place on the mortar layer I2, then disposing the end bricks I4 in place against the end anges 8.and 9 of the frame, and then imbedding the pins D in the mortar imposed on the bricks I4, theframe A will be self-supported so as to relieve the brick layer ofthe necessity of holding the frame inplace until the succeeding layers of brick I5 and I6 are set in place; the lower pins D then affording suiiicient anchorage Ato retain the frame A in a properly aligned position.

By forming the slots C of. a length exceeding the thickness of a brick and with their lower ends spaced from the lower flange I a distance less than the thickness of a brick, the pins D may be readily disposed in'a properposition to align with the mortar joints between 'contiguous courses Aof the b-rick, whether the frame be set on a full brick course as shown in the drawing or on a split course.

I claim: l l

1. A frame for ashpit doors having a lower ange and end flanges, each of said end iianges having through-it a slot which extends longitudinally said slot being of a length exceeding the thickness of. a brick and the lower end of said slotsA being spaced from said lower flange a distance less than the thickness of a brick, and

, l'o'osepins insertable through said slots and adjustabley longitudinally of them for positioning in mortar joints between courses of brick-work, said mortar joints vextending into the brick-work from a wall surface abuttingsaid end anges.

2. In a furnace structure, a door frame having a lower ange and end flanges, each of said end flanges having through it a slot which extends longitudinally thereof, said slot being of a length exceeding the thickness of a brick and the lower end of said slot being spaced from said lower flange a distance less than the thickness of a brick, courses of brick work having mortar spaces between them, the outer ends of said mortar spaces being in an abutting relation to said frame, there being mortar in said spaces, and pins in said slots and projecting into said mortar spaces in parallel relationl to said courses of brick.

3.
